NASA Announces They Will Go Back to the Moon
NASA announced that they will go back to the Moon and set up a base there by 2020. The decision to go back was influenced by the signing of the Space Policy Directive 1, in 2017 by President Trump, stating, “It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use. This time, we will not only plant our flag and leave our footprints — we will establish a foundation for an eventual mission to Mars, and perhaps someday, to many worlds beyond.” (Link)

Scientists Redefine the Kilogram
For over 100 years, the kilogram was defined as the weight of a physical piece of metal in a Paris laboratory. An issue with this is that if that piece of metal gains weight by collecting dirt or dust, or loses weight by scraping it during a measurement, its mass changes which technically changes the value of the kilogram for the entire world. To fix this issue, it will now be defined with the use of a fundamental physical constant, the Planck constant, to keep the value consistent. (Link)
